Application filed y July 8,

My invention relates to automobile attachments and particularly to an attachA ment tor a standard type ot automobile by' which a machine tool may be carried in oper* ative position by the automobile and driven by the power plant thereof.

i am aware. that it is old in the art to provide saw attachments adapted to be driven trom the power plants of automobiles and also which may be carried by the automobile but so 'far as I am aware none of these attachments provides means whereby the attachment may be carried by the automobile in continuous position for immediate use, but ready detachment, whereby the vautomobile provides not only the power plant butthe running gear for the tool and this without in any way modifying the structure ot the automobile or preventing it with the saw attached in operative position from be ing used for its customary purposes.

An object of my invention, therefore, is to provide a self` contained saw attachment to a standard design of automobile which requires no structural changes in the automobile.

.A further object oit my inventionis to provide such an attachment as may be continuously attached to the automobile without in any way interfering with the usual or customary uses of the automobile or in any way reducingits load space or in any way preventing customary access yto any of its operativeparts.

A further object oil. `my invention is to provide such an attachmentas will. be carried bythe automobile in such manner that the automobile supplies the running gear for the attachment whereby the attachment may be moved in operative position from place toplace as the `circumstanci-is of itsparticular work may require.

A further object otmy invention iste so support the attachment as to bring the strains upon the z .iutomobile` structure kwell within the wheel tracks thereof to prevent stress 'for which the automobile V`structure was not vdesigned from being exerted upon its Structural members, -.while atthe same time to support 'the saw in an otset position Vrelalti've to the A=`body ofthe" automobile l whereby the device is maintained in a' position 'for convenient use Y without "danger fof interference om close-proximity eithe Vauton'iob'ile structure or danger of u ry'Y toi-the #auto posite frame 192e.

mobile 'from contact with material used in the tool.

An example oi a preferred embodiment of my invention is illustrated in the accompanying drawings', in which Figure 1 is a 'liront elevation of an automobile with the attachment operatively connected thereto. i

Figure 2 is a side elevation or" the fore part of an automobile with the attachment operatively connected thereto, parts ot vthe automobile structure being broken away or removed to more clearly illustrative the structure.

Figure 3 is luetrating the Figure 4 is luttrating` the a detail partly in section ilaxle connection.

a detail partly .in section illampbracket stay.

Figure 5 is a detail partly in lsection villustrating the shaft connection.'

In the drawingsfl 'is an automobile ot a familiar type having a `front axle 2, front wheels 3 and 4, ahood5, a ra-diator'6,lamp brackets 7, a crank shaft 9, acrank clutch 10, a clutch collar 8, and an engine 11, all of these elements being standard unmodified parts of the particular type or" automobile illustrated. i

Secured to and resting upon the front axle 2 and projecting forwardly therefrom..

I provide a pair of parallel Vhorizontal spaced apart arms 12 and 18, said arms each being secured to the axle by a yoke 18 comprisingbolts 14 and 15, a plate 16 and nut-s 17 and 18. Said yokes are so positioned upon the axle as to bring 'said varms well within the wheel tracks of the automobile. Riveted or otherwise suitably Asecured to said arms are a pair of vertical parallel rear frame supports '1.9 and beyond 4these secured at the forward end of said arms are apair of vertical, parallel front iframe supports-Q0.

Connecting the vforward `frame supports 2O and extending beyond-them to the right- (in Fig l) isfaI horizontal frame member 21, fsai'draine memben'extending to a point considerably.beyond the right hand (inlFig. 1) wheel track of the automobile. Connecting the rear iframe supports 19 and *coexti'ein'slivel .with the ffram'e .member 21 isa-'frame nieinberf.

frlroiningithe ripper partsl of theframe supports 19 with the upper parts of theopvsupnport's 2U .are crossl iframe member-s 2% loo Connecting the lower ends of the frame supports 20 is a bridge niece 25, said bridge piece having angularly upward extending ends and a horizontal center. A lilre bridge piece connects the lower ends of the frame supports 19. These bridge pieces serve not only as bracing for the frame but provide journal saddles as hereinafter mentioned.

Connecting' the frame supports to. the frame members I provide angled cross bracing' 24: and connectingthe forward and rear frame supports to each other I provide an- `ejled bracing 2st.

I prefer to construct the frame work mentioned of that structural steel shape known as angle iron not only to provide a rigid structure but because a frame of this coustruction presents little wind resistance and does not interfere with the effective surface of the automobile radiator.

Projecting upward vertically frame members 2l and 22 I provid 26 and 27 and upon these brackets a horizontal saw table 2S.

lIournaled in any preferred manner upon the frame members 2l and 22. beyond the right hand (in Fig. l) wheel tread of the automobile is a saw shaft 29 carrying a circular saw 30. said saw being positioned in front of the frame member 2l.

I prefer toprovide the saw table with a range 31 and a saw ,enard 32.

Connected with the saw table and the frame member 21, preferably by the bracket from tl ae brackets i support 27. is a tubular member and telescopinu within the same is an adjustable leg Means shown as a set screw 35 retain this leg' in elevated or extended position.

.lonrnaled in any preferred manner upon the bridge pieces 25 is an extension shaft 86 positioned diametrically opposite and formino; an extension of the cranlr shaft of the automobile engine 1l and connected thereto by the collars of the clutch 10, the latter beine' the usual clutch collar provided for the cranking' handle. which .is removed. rihe end of the shaft 36 has a pier 37 which has a wedg'inp; fit in the clutch collar by which the extension shaft may be operati vely connected. to the crank shaft or disengaged therefrom. rThe usual cranking handle of the automobile. not shown, may be fitted to the end of the extension shaft 38 if desired.

Upon the extension shaft 36 is provided pulley 39 and opposite this upon the saw shaft 29 is a pulley 40. these pulleys carrying a belt 4l by which the saw may be driven.

Secured to the frame supports 19 at a position adjacent to their lower ends are a pair of stay rods 42. These stay rods have hooked ends 4:3 to engage the usual lamp brackets '.7 of the automobile. rIlhe rods are connected to the frame supports by adjustable ineans Shown as an adjustable nut connection, whereby the stay rods 42 may he put under tension thereby slightly flexing the frame and preventing` vibration.

The operation of my device is as follows:

T he attachment is always in operative position upon the automobile, although readily removable therefrom. lVhen it is desired to use the saw, the set screw is loos-- ened permitting the leg 34- to touch the ground. The set screw is then tightened. Connection is made between the crank shaft and the extension shaft at the clutch l0 and the engine started. thus driving` the saw.

lVhen it is desired to drive the automobile from place to place or to change the posii-.ion of the saw, it is merely necessary to raise the lee' 34 and move the autotmobile upon its wheels. the shaft connections remaining engaged or may be disengaged as desired.

It will be seen that no structural changes are-necessary in the automobile itself and the attaclunent interferes in no way with the ordinary uses ofthe automobile.

llifhile I have described and illustrated my invention in connection with a circular saw to which it is particularly well adapted, it is not my intention to limit the application of my invention to saws, as it is, with slight modification adapted to be used with any shaft driven implement or tool adapted to be supported by an automobile.

lVhat I claim to be new is:

l.. In a device of the character described. arms adapted to be supported from and in forwardly projectingl relation to the front axle of an automobile7 a lattice frame so supported on said arms as to be positioned in advance of and spaced from the hood of the automobile between the wheel tracks thereof. a saw table overhanging one side of said fran'ie whereby a saw jonrnaled in said frame. is positioned at the side of and beyond the wheel track of the automobile with its cuttingr plane transverse to the trackway of the automobile so that both ends of the table will be free for receiving and delivering; the work, and means for connecting' the saw operatively to an extension of the cranhY shaft of the automobile power plant.

2. A. vehicle attachment including a frame havinga pair of spaced substantially horizontally disposed transversely eXtendinf bars in advance of the radiator of the vehic-le projecting! laterally of the latter, npright members in substantial alignment with the radiator of the vehicle supporting said bars, longitudinally extending rails connected to pairs of said upright members having their rear ends resting on the front axle of the vehicle. means extending between the vehicle and frame for retaining said rails on saidaxle, a saw carried by the lateral portions of said bars, and a driving connection between said saw and the crank shaft of the vehicle including said frame.

3. A vehicle attachment including a frame having a pair of spaced substantially horizontally disposed hars in advance of the radiator of the vehicle projecting laterally of the latter, upright members in substantial alignment With the radiator supporting said bars, longitudinally extending rails connected to pairs of said upright members having portions thereof carried hy the front axle of the vehicle, means extending between the vehicle and frame for retaining said rails on said axler` bridge hars connecting pairs of said upright members, a saw `iournaled in hearings on the lateral portions of the first mentioned hars, a shaft jonrnaled in bearings on the bridge hars in substantial alignment with and connected to the crank shaft of the vehicle, and a driving connection hetween said shaft and saw.

4;, The combination with a .motor vehiclel` of an attachment therefor including a frame having spaced longitudinally extending hars mounted on the forward axle of the vehicle, a cross har carried by said longitudinally extending hars, a drive shaft in alignment with and connected to the crank shaft of the parts carried by vehicle journaled in hearings on said cross har, spaced cross hars mounted on the hars aforesaid above said shaft, a tool shaft parallel to the crank shaft of the Vehicle earried hy the last mentioned cross hars, and a driif'ing connection between said first and last mentioned shafts.

The combination With a `motor Vehicle, of an attachment therefor including a frame having spaced longitudinally extending bars mounted on the front axle of the vehicle, spaced transversely7 extending hars carried by the oai aforesaid1 a drive shaft in alignment with and mmnected to the crank shaft of the vehicle joi'irnalled in hearings on said transversely extending ha spaced cross hars mounted above and carried by the hars aforesaid and having portions extending laterally of the vehicle, a tool having a driving shaft parallel to the crank shaft of the Veliicle journaled in bearings on the last mentioned hars, a work table extending longitudinally of said cross hars, and a driving connection between the lirst and last mentioned shafts.
